Today with the presence of number of hackers or intruders, it becomes crucial to make a well protected shield around the network. It's not easy to maintain a secure small business network but with some useful and effective tips, you can secure your data and network at great extent.

Intruders can use it to access the network and can leave some dangerous threats over the network. Some people use MAC addresses filtering or lock down the Mack address for security. But rather than this, one more secure way is the use of WPA2 encryption. It is far better than other encryption methods.
- Hide SSID: Make sure to hide service set identifier if you using wireless network. Most of the routers broadcast the network's name of SSID. But rather than broadcasting real information which gives the clear information about who owns the router, hide the SSID or give a different name like router1 or anything else. Don't give your business name or any other informative name that gives any kind of information to intruder. You can turn off SSID broadcast for network which makes it invisible to all nearby people.
